Sorry for the long story but I need to put my OEM OS back into the PCM. Below are some details if you are bored and want to look....
My Question?
How do I get an OEM file back into the PCM? Do I Write (Entire) my modded file I got from a Mail Order tuner? Then Write (cal) the data from a stock file from the repository? Or is there a better, smarter, safer way to get it back. That is the direction I need to go ? a complete Do-Over.
Thanks for any insight here. It?s now winter in PA so I have a little time before I get to drive it again. I hate to put it to bed without it being ?right? but I have a LOT of plans for other work on the car. Look for it at Woodward in ?24. ;+)
The Project
Late 03 Z06, LSA Blower, Phenolic Rect to Cath port adapters (OKW), P01 (411) PCM, ECS stage 1 Fuel pump plumbed like UPP does it (Regulator, feed into Schrader port, ECS Bulkhead fitting for return to Dr Side tank), Deka 60 Shorties, BTR Stage 3 PDS Cam, Long Tubes, All the Fix?ns, Stock Bottom End.
Beginning?
I sent the PCM to a well-known Supercharger Company on the East Coast. When I got it back the car would not start. Went Round & Round with them, Did not end well. I did not have HPT at that time ? now I do. They never gave me a copy of my OEM tune file. I do have a copy of what they did & It appears that it is just a Modded Stock file. I can see all the OS choices and HPT recognizes it as MY licensed credits. That OS is 12593358 and I have it licensed with HPT
Middle?
I hooked up with a pretty sharp guy that knows what he?s doing to tune it. I?m in PA ? He?s in OR. He sends data, I load and log, he tweaks it ? rinse & repeat. It was starting to run pretty good. THEN? He figured he had the wrong injector data in the file and swapped it out with the new, Banish approved file. I cannot say enough NICE about Bob at FIC (Connection). HE sent the latest file for the Deka 60?s. Once that was loaded the thing turned to pure Crap. Some think it?s the Adapters causing problems but old tunes worked better than ?new? ones. The current OS is a custom 3 BAR SD that replaced the OEM once we got started tuning for boost. That OS is 1263016.
Now?
I was asked by a Pro Tuner that FIC hooked me up with to put a stock file back in and start over. This guy is the Real Deal and I will do what he says.
When I look at the read / write icon for the repository file it invites me to but a license for it. I'm not sure I can even copy the guts to my Modded File. The Mail order guy made LOTS of changes according to a compare of the 2. How do I merge them and not get a brick??
Thanks again - sorry to be so wordy. It's a curse.
Here's 2 pics of the project.
